Switch
On: The switch will monitor and address
loop-related issues within the network
structure to prevent disruptions caused by
redundant pathing
O: (default) The switch will not try to
monitor or address loop-related issues

The Power LED should be lit when the power system is working normally. If
the Power LED is not lit, check as follows:
A1:
Make sure the power adapter is connected to the switch with power
source properly.
A2:
Make sure the voltage of the power supply meets the requirements of
the input voltage of the switch.
A3:
Make sure the power source is ON.
Q1. The Power LED is not lit.

Q2. The right and left LED are not lit when a device is
connected to the corresponding port.
It is recommended that you check the following items:
A1:
Make sure that the cable connectors are rmly plugged into the switch
and the device.
A2:
Make sure the connected device is turned on and works normally.
A3:
The cable must be less than 100 meters long (328 feet).
Q3. Why does the switch fail to detect and block a loop
from occurring in the network topology when Loop
Prevention is enabled?
A:
When connecting this switch to other non-terminal devices, such as
switches from other brands, and those devices cannot properly process
or forward loop detection packets, the Loop Prevention function may be
limited. It is recommended to connect terminal devices directly to this
switch or use non-terminal devices with full forwarding capability.
